Hi Jonathan, thanks for the reply.
I am using a Arduino Uno with a breakout shield.
I have tried various steppers with various voltage.
I have LEDs i series with the coils which light up as each coil is energized.
Power is bu USB to the arduino and a variable Voltage 10 amp power supply for the Stepper Vmot.
Breadboards do not make for “clear” pictures, but here you go.
I was not getting Vref until today, I set Vref at .58 volt.
